heterogeneous service location service architecture based on OSGi technology

In recent few years, a lot of standards and protocols have been proposed for home networks. However, these standards and protocols do not interconnect easily with each others. This paper describes the service discovery and interaction for home network devices using heterogeneous standards and protocols. OSGi was proposed to provide several kinds of services coming from different providers to be loaded and run on a service gateway. OSGi also defines open specifications and standards for the delivery of managed services to networked environments. In this paper, we propose an OSGi based control architecture for smart home network. We use OSGi as a platform, on which to combine the component of the SLP SA/DA, the UPnP control point and the SIP UA, to achieve automated devices discovery, registry, and management. Finally, application examples are introduced and the implementation results show that our proposed architecture, the OSGi gateway can provide automatic heterogeneous devices and service management.
